Forward error-messages from folder panel. E.g. currently when dropping something above a read-only folder in the folder panel no feedback is given.

Remember column-widths per directory when changing it by the user. Don't forget a kind of "Reset"-entry in the context-menu to make it possible to use the auto-expanding again (see bug 264434)

Missing Dolphin 1.x Features

Dolphin 1.x features that are still missing in the master branch belong here.

Moving of columns in the details view. Would be great having it back for 2.0, but let's fix the open other issues first before starting with this. Fixed for 4.8.2 (Bug: 164696, Commit: b62c74ec4cc891bc5fafeeafe67dbcc1d17fd445)

Inline renaming is not possible. It is planned for 2.1 to make inline renaming default and to solve the missing "OK"/"Cancel" issue (some people have problems to finalize the renaming by pressing RETURN with the inline renaming from Dolphin 1.x).

Horizontal autoscrolling for the Folders Panel. Won't be implemented for 2.0 anymore: Let's wait for feedback first - if the autoscrolling will be requested again let's bring it back in 2.1.

No selection toggle in the group headers.

Known Bugs

Known regressions in the master branch are listed here.

Holding Shift + mouse wheel scroll doesn't increase scroll rate like it does in any other KDE app.
